# For pull requests, only the latest workflow run is allowed to proceed.
# Older runs are canceled when a new revision is pushed.
#
# For pushes, if more than one workflow run is triggered for the very same
# commit hash (which happens when multiple branches point to the same commit),
# only the first one is allowed to run. This allows a successful completion of
# the first run to be reused in the second run via the `skip-if-redundant`
# logic in the `config` job.

# For more details about the `concurrency` attribute, see:
